The Costarina faunas of Panama and Colombia are revised. Because Chickering described the sexes from his Panamanian collections separately, several of his names based only on females are placed as junior synonyms of names based only on males: C. humphreyi (Chickering) is newly synonymized with C. recondita (Chickering), as are C. belinda (Chickering) with C. intempina (Chickering), C. rigida (Chickering) with C. abdita (Chickering), C. silvatica (Chickering) with C. dura (Chickering), and C. improvisa (Chickering) with C. seclusa (Chickering). The Costa Rican species C. pittier Platnick and Berniker is newly recorded from Panama. Nine new species are described from Panama (C. sorkini, cerrocol, bocas, chiriqui, clara, fortuna, almirante, dybasi, and tskui), as are 11 from Colombia (C. sasaima, suiza, otun, choco, yotoco, saladito, antonio, anchicaya, gorgona, helechal, and taraira). Previous studies on more northern species are supplemented; newly available collections from Nicaragua reveal the presence there of two new species (C. kilambe and diablo), and locality records are provided for the Costa Rican members of the genus.
INTRODUCTION
One of the problems confronting students of goblin spiders, and other sexually dimorphic organisms, is correctly matching males and females, especially when two or more congeneric species occur sympatrically. The problem is well exemplified in the treatments by Chickering (1951, 1968) of the Panamanian species now placed in the genus Costarina Platnick and Dupérré (2011). Chickering described no fewer than 13 species of this genus from the collections he made, over many years, at just a few sites in Panama; however, seven of those names were based only on males, and six were based only on females. In some cases, Chickering even collected the two sexes together; for example, in August of 1950 he collected two males and four females “during the same short period of nine days in Boquete” (1968: 9). These were the only specimens of Costarina Chickering collected at Boquete during that 1950 expedition; he described the females as Dysderina belinda. Later in the same paper, he described the males as Dysderina intempina, commenting (1968: 20) that “Females taken at the same time and in the same locality may also belong here but there can be no certainty at this time.”
Although Chickering's statement is literally true, it misses the target. First, in this case, there is at least one morphological character suggesting that the two sexes that were collected together are indeed conspecific: they share an unusual, complexly shaped posterior sternal ridge (fig. 18). More importantly, though, Chickering's approach resulted in a seriously flawed estimate of the total diversity of Costarina species found in his collections. Hypotheses matching the sexes, in any particular case, may prove to be erroneous, of course; there is no more “certainty” involved in these hypotheses than in those concerning the characters thought to differentiate species. The most “certain” outcome of Chickering's approach, however, is grotesquely inflated estimates of an area's biodiversity As one would expect, in this case the six names based only on females each appear to be mere synonyms of the various species Chickering also described from males. The unparsimonious approach adopted by Chickering virtually guaranteed that roughly half of his names would become synonyms (cf. Edwards, 2013).
In Chickering's case, the misguided search for “certainty” resulted in problems at higher taxonomic levels as well. His unwillingness to match males and females he had taken together precluded his discovery that some of the characters previously used to group species and genera of goblin spiders are actually sexually dimorphic (for details, see Bonaldo et al, 2014).
In the present paper, we complete our coverage of the speciose genus Costarina by revising the species found in the most southern part of the generic range, Panama and Colombia. We also take the opportunity to update previous studies of the more northern species (Platnick and Dupérré, 2012; Platnick et al, 2014), to provide detailed locality records for the Costa Rican species not presented in the latter paper, and to offer some comments on interrelationships among the many species involved.
The new taxa supply some novelties. For example, in both sexes of C. choco, new species, from Colombia, the dorsal scutum has fused to the epigastric scutum, a feature found in some other members of the Dysderina complex (see Platnick et al, 2013a: 5) but not previously noted in any Costarina species. Although fusion of the epigastric and postepigastric scuta is universal among males of the genus, females with fused ventral scuta were previously known only from Costa Rica (and further south, as detailed below), but one of the new species described below from Nicaragua also shows that unusual feature.
Understanding relationships within Costarina is a complex problem, not only because the genus is so speciose (now containing 108 species), but because many of the species remain poorly known—13 species are known only from males and three are known only from females. Given the large number of potential clades of two or more species, and that the species are at present differentiated almost entirely by genitalic details, it isn't likely that anything close to a fully resolved cladogram will be obtainable soon. Even if we succeed in identifying features of the male palps that are actually synapomorphic for some subgroup, the likelihood of finding an exactly congruent genitalic character among the many females is low, and hypotheses of the monophyly of any of the groups will be suspect simply because of the species that are not yet known from the relevant sex.
Nevertheless, we have attempted to recognize some species groups. For example, there are seven species (abdita from Panama and chonta, cima, cuerici, poas, rafael, and san from Costa Rica) in which the distal prong of the male embolus is enlarged, fan shaped, and clearly divided into distal sclerotized and proximal translucent portions, and the proximal prong is reduced to a small projection that is largely hidden behind a prolateral fold of the distal prong (fig. 26). The females of these species share a thickened anterior atrial border, a reduced atrium, and (except possibly in chonta) a W-shaped sclerotization that extends posteriorly between the apodemes (fig. 33).
Four other species from Costa Rica (aguirre, alturas, isidro, and monte) share the distalprong features of the abdita group, but the proximal prong is normal in size and position, and (in all save aguirre) notably narrowed, elongated, and sharply pointed (Platnick et al, 2014: fig. 259). Of these species, the females share a thickened anterior atrial border and all save monte have the posterior W-shaped sclerotization and a normal (rather than reduced) atrium. This group could thus be paraphyletic relative to the abdita group.
Five further species resemble those of these two groups. Two of them (junio and macho) seem to be sister species, sharing a spiraled distal prong (Platnick et al., 2014: fig. 294) that, like those of intempina, palmar, and parapalmar, is not fan shaped but is enlarged and divided into sclerotized and translucent portions (figs. 12, 14). Females of parapalmar are unknown, but those of the other four species resemble those above in having a notably thicked anterior atrial border and the posterior W-shaped sclerotization; the atrium is reduced in all save junio.
Another seven species from Costa Rica and Panama have the distal prong divided into sclerotized and translucent portions (figs. 80, 136) but unexpanded (clara, frantzius, leones, nara, obtina, osa, and seclusa); in all save leones and obtina, the proximal prong is long, narrow, and sharply pointed. The known females share the notably thickened anterior atrial margin and the posterior W-shaped sclerotization, and we therefore suspect that all of the above species may form a monophyletic group; each of the subgroups might be paraphyletic relative to those preceding their discussion (except for the first-discussed abdita group).
Some pairs of species share notable genitalic modifications. Perhaps the most obvious are two sharing an embolus that is long and narrow, with no trace of a separate proximal prong (pittier and reventazon, Platnick et al., 2014: figs. 306, 465). The female is known only for pittier, and it resembles those of the above-discussed groups. Another such pair (coma from Honduras and helechal from Colombia) share a long, sinuous proximal prong that is widely separated from a long, relatively narrow distal prong (fig. 241). The geographic disparity suggests that the similarity may be misleading; unfortunately, females are known only for coma. Another pair of possible sister species from Costa Rica share a wide, straight proximal prong that is overlaid, in ventral view, by a lobe of the distal prong (jimenez, ubicki; Platnick et al, 2014: figs. 498, 542); males of two other species (chiriqui from Panama and gorgona from Colombia) have a similar embolar conformation but differently shaped proximal prongs (figs. 77, 230). Two other species from Costa Rica (ramon, upala) may be sister taxa, sharing an oddly cap-shaped, retrolaterally protuberant distal prong (Platnick et al, 2014: figs. 104, 105, 247, 248).
Similarly odd are two Costa Rican species that have deeply bifid dorsal prongs, the distalmost portion of which is subdivided into rounded basal and sharply pointed terminal portions (azul, cruz; Platnick et al, 2014: figs. 160, 331). Females of this species pair share fused ventral scuta, a greatly thickened anterior atrial border, and a widened base of the anterior genitalic process (Platnick et al, 2014: figs. 165, 336). The deeply bifid distal prong is found also in a large group of species from Costa Rica and Panama (almirante, carrillo, elena, hitoy, meridina, mooreorum, murphyorum, penshurst, pity, and selva; figs. 94. 95). There may be two subgroups involved; in one (meridina, murphyorum, selva) the distalmost prong is long and narrow, whereas in the others it is distally expanded. There seems to be little that unites the females of these species, although some members of each subgroup (such as selva and carrillo) have such autapomorphic female genitalia that detecting any close relatives is problematic. Males of three other species (cerere and chiles from Costa Rica, plus dybasi from Panama) have the dorsal prong appearing more trifid than bifid (fig. 106), and maybe members of this group, or perhaps its sister taxon; females of all three species have an anteriorly widened anterior genitalic process (fig. 112).
Such highly unusual female genitalia do sometimes suggest relationships, however. For example, three species (bocas from Panama, plus choco and yotoco from Colombia) share a posterior genitalic atrium and an enormously expanded tip on the anterior genitalic process (figs. 65, 191), and their known males do share a medially excavated distal embolar prong (figs. 60, 186). Such an excavated distal prong may be shared with four other species (carara, gemelo, and parabio from Costa Rica plus kilambe from Nicaragua; fig. 250)
Among the remaining males, those of three species (semibio from Costa Rica, cerrocol from Panama, and saladito from Colombia) share an embolar conformation in which both the proximal and distal prongs are long, narrow, approximate, and largely parallel (figs. 49, 197). There are several species with a similar conformation, but with the two prongs more widely separated, including iviei, llama, oaxaca, and naja from Mexico, plus barbilla and maritza from Costa Rica; Platnick et al, 2014: figs. 38, 313).
Finally, there are numerous males that share the embolar conformation of the type species, plena, with a relatively short, often distally bent distal prong closely accompanied by the proximal prong, which is often retrolaterally expanded (as in fig. 38); such species resembling plena include mixtepec, subplena, sepultura, and bochil from Mexico; peten, macha, and morales from Guatemala; cortes, cofradia, cusuco, tela, ceiba, branstetteri, olancho, muralla, and gracias from Honduras; waspuk, musun, blanco, and diablo from Nicaragua; paraplena, superplena, watina, and concinna from Costa Rica; recondita, sorkini, and fortuna from Panama; plus sasaima, suiza, and otun from Colombia. Of course, it is possible that this conformation represents the plesiomorphic form for the genus; the known females of these species do tend to have relatively unmodified genitalia.
Our methods follow those of Platnick and Dupérré (2009); only differences from the males (beyond the obvious lack of male endite modifications) are mentioned in the descriptions of females. Scans were taken from uncoated right male palps, and the images were flipped for consistency. The taxa are treated in geographic order, beginning with the three species that occur in Costa Rica as well as Panama, and proceeding southward. All measurements are in mm; high-resolution versions of the images, a sortable version of the geocoded locality data, and a distribution map for each species (with dots linked to the specimen data) will be available on the goblin spider Planetary Biodiversity Inventory (PBI) project's website ( http://research.amnh.org/oonopidae). Users should note that the relatively small published images are merely avatars for the actual image files on the website, which can each be enlarged several times before pixelating.

Costarina Platnick and Dupérré, 2011: 50 (type species by original designation Dysderina plena O. P.-Cambridge, 1894).
Diagnosis: Members of Costarina can be recognized by the presence of three transverse sternal ridges together with the absence of grooves connecting either the anterior or posterior pairs of spiracles (see Platnick and Dupérré, 2012: 3).
Description: For all characters not mentioned here, see Platnick and Dupérré, 2012: 3. Total length of females 1.7–2.8. Posterior portion of pars cephalica usually with large, U-shaped smooth area, but smooth area reduced in females of C. anchicaya, cerroco, diablo, dura, dybasi, gorgona, intempina, kilambe, recondite, saladito, sasaima, seclusa, taraira, tskui, yotoco, absent in females of C. almirante, reduced in both sexes of C. antonio, bocas. ALE separated by roughly their radius. Anterior margin of sternum usually with continuous transverse groove, but groove interrupted medially in at least C. antonio, gorgona, kilambe, otun, saladito, suiza, taraira, yotoco; surface of sternum with three transverse ridges connected by median longitudinal ridge, longitudinal ridge usually with anastomosing branches but sometimes simple or weak, rarely reduced to connecting only two anteriormost transverse ridges or virtually obsolete. Cheliceral retromargin usually without tooth. Serrula apparently absent (scanned only in C. plena). Dorsal scutum of males usually covering full length, width of abdomen, fused to epigastric scutum in C. choco, of females covering from 3/4 to full length, width of abdomen. Postepigastric scutum of males usually extending to nearly full length of abdomen; postepigastric scutum of females almost semicircular, usually free, but fused to epigastric scutum in C. almirante, antonio, bocas, choco, dybasi, gorgona, kilambe, otun, sasaima, seclusa, sorkini, taraira, tskui, extending to at least 2/3 of abdomen length. Spinneret scutum present as incomplete ring with fringe of long setae in females, but often reduced to narrow rim or detectable only by setal positions in males.

Costarina cerrocol,
new species
Figures 45–55
Type: Male holotype taken from a stage IV stump with passalid burrows at an elevation of 1220 m on Cerro Colorado, Chiriqui, Panama (Jan. 8, 1981; W. Suter), deposited in FMNH (33666, PBI_OON 10168).
Etymology: The specific name is a noun in apposition shortened from the type locality.
Diagnosis: This species appears to be a northern vicariant of C. dura, sharing an obliquely oriented proximal prong on the male embolus and a shortened postepigastric scutum in females, but can be distinguished by the narrower, sharper distal embolar prong of males (figs. 45–50) and the sinuous, slightly recurved posterior margin of the genital atrium of females (figs. 53–55).
Male (PBI_OON 10168, figs. 45–50): Total length 1.83. Endite processes both long, sharply pointed, tips widely separated. Leg spination: femora: I p0-1-1, rl-1-1; II p0-1-1, rl-1-0; tibiae I, II v4-4-lp; metatarsi: I v2-2-lp; II v3-0-2. Embolus with both prongs narrow, parallel to each other.

Distribution: Northern Panama (Chiriquí). The species may also extend further south, as we have seen two females that resemble those from Cerro Colorado but have the genital atrium slightly shorter and wider. The data on those specimens is as follows: Veraguas: Leren, Bahía Honda, Dec. 7–18, 2001 (R. Miranda, MIUP PBI_OON 37744); Panamá: Cerro Campana, June 5, 1995, wet montane forest litter, elev. 950 m (R. Anderson, AMNH PBI_OON 51457). Males from those localities are needed to determine whether this species actually has a larger than usual range.

Costarina dybasi, new species
Figures 102–112
Types: Holotype male, allotype female, and paratype female from Berlese sample of concentrated floor litter taken at Almirante, Bocas del Toro, Panama (Mar. 27, 1959; H. Dybas), deposited in FMNH (33654, PBI_OON 10156).
Etymology: The specific name is a patronym in honor of the collector, Henry Dybas of the Field Museum of Natural History.
Diagnosis: Males can easily be recognized by the trifid distal embolar prong (figs. 102– 107), females by the fused ventral scuta and recurved genital atrium (figs. 109–112).
Male (PBI_OON 10156, figs. 102–107): Total length 2.07. Endite ventral process small; dorsal process with narrow, medially directed tip. Leg spination: femora: I p0-1-1, r1-1-0; II p0-0-1; tibiae: I v4-4-2; II v4-4-1p; metatarsi: I v2-2-2; II v3-0-2. Embolus proximal prong long, narrow; distal prong trifid.
Female (PBI_OON 10156, figs. 108–112): Total length 2.09. Leg spination: femora I, II p0-1-1, r1-1-1; tibiae: I v4-4-2; II v4-4-1p; metatarsi: I v2-2-2; II v3-0-2. Genital atrium recurved, almost boomerang shaped, anterior genitalic process distally flared, posterior genitalia with conspicuous lobes visible through cuticle.
Other Material Examined: PANAMA: Bocas del Toro: Changuinola, July 30, 1981, forest litter (G. Edwards, FSCA PBI_OON 51508), 1♀.
Distribution: Panama (Bocas del Toro).
Costarina tskui, new species
Figures 113–123
Type: Holotype male taken at an elevation of 800 m at a site 1.5 km east of the Río Tskui, Bocas del Toro, Panama [near Yorkín, Limón, Costa Rica] (Oct. 27–29, 2008; M. Moraga, A. Solis), deposited in INBIO (PBI_OON 37019).
Etymology: The specific name is a noun in apposition taken from the type locality.
Diagnosis: Males and females have not been collected together and may be mismatched. Males can easily be recognized by the extremely narrow proximal embolar prong (figs. 113– 118), females by the fused ventral scuta and large, rounded genital atrium (figs. 120–123).
Male (PBI_OON 37019, figs. 113–118): Total length 2.13. Endite prongs both with long, narrow, anteriorly directed tips. Leg spination: femora: I p0-1-1, r1-1-1; II p0-1-1, r0-1-0; tibiae: I v4-4-2; II v4-4-1p; metatarsi: I v2-2-2; II v3-0-2. Embolus proximal prong basally enlarged, thin, needlelike throughout most of its length; distal prong wider, distally rounded.
Female (PBI_OON 81, figs. 119–123): Total length 2.20. Leg spination: femora I, II p0-1-1, r1-1-1; tibiae: I v4-4-2; II v4-4-1p; metatarsi: I v2-2-2; II v3-0-2. Genital atrium long, with recurved posterior margin; anterior genitalic process narrow, distally flared.

Notes on More Northern Species
Previous papers dealt with the Costarina species found from Mexico south to Nicaragua (Platnick and Dupérré, 2012) and with those known from Costa Rica (Platnick et al., 2014). Newly available collections resulting from the Leaf Litter Arthropods of Mesoamerica project (LLAMA, see http://llama.evergreen.edu/) allow us to present here substantial new information on the Costarina fauna of Nicaragua; previously only three endemic species (plus the widespread species C. plena) were known from that country. We also present here full locality data on Costa Rican species that were omitted from part 2 of this series (Platnick et al., 2014).
